# Configure the Filter Function

1. Add a Filter function to the spreadsheet and open its property sheet.
2. Select the Region parameter and press the Maximize Region button so that the region covers the entire image.

3. Set the Filter Type parameter to Binarize.

4. The image will then be output into all black or all white pixels, using a "binary" threshold operation that compares each input pixel with the threshold level to determine whether the output pixel is white or black. Input pixel values equal to or above the Threshold parameter value are white; values below the threshold are black.
